INOUIRY
- Plano concave lens is an optical lens with one flat surface and the other concave surface. These lenses are primarily used for beam divergence or optical path adjustment, and are commonly found in optical systems, laser equipment, telescopes, microscopes, and other optical instruments.
These plano-convex lenses are also available in uncoated versions and versions with three broadband antireflective coatings: A-coating (350-700 nm), B-coating (650-1100 nm), or C-coating (1050-1700 nm).
